Band theory of Co₂MnSn, Co₂TiSn and Co₂TiAl

Photoelectron spectroscopy of manganese-based Heusler alloys

“…31 Investigating each alloy in more detail, the Co containing sample will be considered first. Figure 2͑a͒ shows the PDOS for the 3d bands of Co 2 MnSn adapted from the symmetrized augmented-plane-wave ͑SAPW͒ calculations of Ishida et al 11 To facilitate comparison between experiment and theory, the bands have been convoluted to model intrinsic and extrinsic broadening. To model lifetime effects, the bands were convoluted with Lorentzians of HWHM varying in proportion with the square of the binding energy from zero at E F to 0.6 eV at the bottom of the band.…”

“…As a consequence, the localized magnetic moments have been interpreted in terms of virtual bound Mn 3d states. 8,9 However, more recent band-structure calculations by Ishida et al, [10][11][12] Williams et al, 13 and Kubler, Williams, and Sommers 14 have indicated that the Mn 3d majority spin states form a common hybridized band with the X d states, while the Mn 3d minority spin states are mostly unoccupied. The localized magnetic behavior, therefore, is explained in terms of exclusion of minority spin electrons from Mn sites.…”

Electronic structure and spectroscopy of the quaternary Heusler alloy Co2Cr1−xFexAl

“…Ferromagnetic properties of various Heusler compounds have been investigated experimentally [11][12][13][14][15][16] and theoretically [9,17] (see Refs. [18,19] for comprehensive review).…”

Tunnel magnetoresistance of disordered, low-moment Co2MnSi Heusler alloy thin films

“…The full-Heusler alloys crystallize in the L2 1 structure that comprises four fcc sublattices. Ziebeck and Webster 2 synthesized full-Heusler alloys containing Co, and Ishida et al 3 predicted the half-metallicity of Co 2 MnSi.…”
